Data Sheet
1. Product Description
2. Applications
The 3M 5451R Quick Splice II is a 25/28 kV class inline
splice designed to serve as a cable repair for concentric
neutral (CN) and jacketed concentric neutral (JCN)
distribution class power cables. It is designed to replace up
to 6 inches (152 mm) of damaged cable, thus eliminating
the need to splice in a new section of cable with two
separate splices.
To make a repair splice on 25 kV and 28 kV class
distribution cables:
The splice is a one-piece molded design made of specially
formulated, peroxide cured EPDM rubbers. Each splice is
production tested on CN cable to ensure reliability. The
splice is designed for use with the special CIR–Series
Inline Compression Connector provided, for connecting
either aluminum or copper conductors. The 5451R Quick
Splice II meets the 25 kV voltage rating requirements of
ANSI/IEEE Std. 404–1986.
Kit Contents:
For inline repair splicing of damaged cable
For cable repairs up to 6 (152 mm) in length
For damaged concentric neutral (CN) cable
For damaged jacketed concentric neutral (JCN) cable (used
with an accessory splice jacket, e.g. 3M SJ–A Series
with additional 8420 Series Cold Shrink Insulator or
3M HSJ Series with additional ITCSN Series Heat
Shrinkable Sleeve)
For fitting cable insulation diameter sizes of 0.870 to
1.055 (22,1 to 62,8 mm)
For direct burial installations
For aerial installations
For submerged locations
1 Molded rubber splice body
1 Connector (CIR–Series)
2 Packets of silicone grease
1 Template
1 Instruction sheet
Splice Features:
One-piece design, for simple installation
Elongated splice body, allows for the removal of up to 6
(152 mm) of damaged cable
Special 3M CIR–Series repair connector, for a one-piece
connection to bridge across the gap resulting from the
removal of damaged cable
Production tested, partial discharge and alternating current
withstand, for long term reliability
Peroxide cured EPDM rubber construction, for long term
elastic memory (sealing) and easy installation
Computer designed, for compact size and optimal
distribution of the electrical field
3. Data: Physical and Electrical
Properties
The 3M 5451R Quick Splice II can be used on distribution
class cables with a rated operating temperature of 90C,
and an emergency overload rating of 130C. Splices made
with this kit are rated for 25 kV and 28 kV and meet the 25
kV rating requirements of ANSI/IEEE Std. 404–1986,
“IEEE Standard for Cable Joints for Use with Extruded
Dielectric Cable Rated 5000 V through 46,000 V.” The
current rating of the splice meets or exceeds the current
rating for the cables on which it is installed. BIL rating of
the splice is 200 kV.
A Special 3M CIR–A or CIR–840 Series connector is
included with the splice kit. It is crimped with a standard
5/8 die or 840 die, respectively. These connectors meet the
requirements of ANSI C119.4–1986, “Connectors for Use
Between Aluminum or Aluminum-Copper Overhead
Conductors.”
